Could you elaborate on that statement... I understand that genetics have
proved that we have all come from common ancestors, and, possibly, that we
are of the same species (the point of contention in my original post), but
does it in any way cast the idea of "strains" or "subspecies" or "races" in
doubt. After all, for example, genetically, I believe, various groups are
susceptible to different illnesses. I have been told that such resistances
are enough to classify micro-organisms, if not higher creatures. Could this
be a basis of further breakdown of our species?
